(2) 动作电压与线圈预通电电压有关,预通电后检查动作电压,其值会变大 (3) 线圈最大允许温度为 180℃,考虑到电阻法所测量的线圈温升是平均值,推荐在 不同使用环境、不同线圈电压、不同负载条件下测量时,线圈温度应小于 170℃. (4) 当线圈实际工作电压超出曲线规定范围时,请联系美硕并提供相应详细使用条件. (1) There should be no contact load applied when maximum continuos operation voltage is applied on coil. (2) The operating voltage is connected with coil pre-energized time and voltage. After pre-energized,the operating voltage will increase. (3) The maximum allowable coil temperature is

180 ℃ .For the coil temperature rise which is measured by resistance is average value,we recommend the coil temperature should be below 170℃ under the different application ambient,different coil voltage and different load etc. (4) If the actual operating coil voltage is out of the speci?ed range please contact meishuo for further details. 说明: (1) 本图以常开触点为例,本图电流为阻性. (2) 产品按接触点参数表进行负载与耐久性试验,当实际使用的负载电压、电流、 动作频率任一项与触点参数表不同时,请重新进行确认试验. (1) This chart takes NO contact,Resistive load as example. (2) The load and electricl enduance tests are made according to CONTACT DATA paremeters , table. lf actual load voltage, current, or operate frequency is different from CONTACT DATA table, please arrange corresponding tests for con?rmation. 线圈电压 ( 额定电压百分比 ) Percent of Rated Coil Voltage 切换电压 (VDC) Switching Voltage 切换电流 (A) Switching Current 环境温度(℃)Environmental Temperature - MEISHUO -
